This thesis mainly studies the digital pulse compression technique and analyses the pulse compression performance of lfm signal with high compression ration . it also simply describes the basic theories of sar imaging and signal processing . based on these theories and high performance digital signal processing chip adsp21160 , we successfully design and realize a frequency domain digital pulse compression system on hhpc board with four adsp21160 embedded 本文主要研究了合成孔径雷达成像技术中距离和方位频域数字脉冲压缩技术，着重分析了高压缩比下lfm信号的脉压性能，简述了合成孔径雷达成像的基本原理和信号处理，在此基础上结合高性能数字信号处理芯片adsp21160研制成功了基于hhpc板的二维频域数字脉冲压缩处理系统。
